Question

510 pen drive were shared among schools x,y,and z has 1 half times as much y and y has 3 times as much as x. Express X share as a percentage of the total

Answer 1

Let:

• School x share be x
• School y share be 3x
• School z share=1(1/2)×3x=9x/2

To Find:

• Percentage of share school x=?

Solution:-

=>Sum of share x y and z=510

=>x+3x+9x/2=510

=>4x+9x/2=510

=>8x+9x/2=510

=>17x=510×2

=>17x=1020

=>x=60

Now calculate here each share get

• School x share=60 pen drive
• School y share=3x=3×60=180 pen drive
• School z share=9x/2=9×60/2=9×30=270 pen drive

Now, calculate the percentage of School x

=>School x share get×100/Total pen drive

=>60×100/510

=>6000/510

=>11.76%

$\tt{\underbrace{Answer-School\:x\: share\:get=11.76\%}}$

Answer 2

Given

Total pen drive=510

Let assume,

School x get=x

School y get=3x

School z=9x/2

sum of x y z=510 pen drive

x+3x+9x/2=510

x=60

so, School x get 60 pen drive

now finding % here

60×100/510

11.76%
